Approach‐Avoidance Motivation and the Use of Affect as Information

Individuals often rely on their affect for information. However, positive or negative affect may not be informative for individuals who are more prone to feel affect of this particular valence in general, unless they chronically monitor their internal states. A series of studies demonstrates that differences in individuals’ internal versus external focus of attention and in trait affective valence associated with their approach versus avoidance motivation determine reliance on affect as information. Specifically, our findings show that while positive affect is used as an input in product satisfaction judgments regardless of individuals’ approach versus avoidance motivation, negative affect is used only by individuals with a predominant approach motivation.     

Implicit probabilistic sequence learning is independent of explicit awareness

Studies into interactions between explicit and implicit motor sequence learning have yielded mixed results. Some of these discrepancies have been attributed to difficulties in isolating implicit learning. In the present study, the effect of explicit knowledge on implicit learning was investigated using a modified version of the Alternating Serial Response Time (ASRT) task, a probabilistic sequence learning paradigm that yields continuous and relatively pure measures of implicit learning. Results revealed that implicit learning occurred to the same extent, whether or not subjects had explicit knowledge. Some evidence, however, indicated that explicit knowledge could interfere with the expression of implicit learning early in training. In addition, there were dissociations between learning measures, in that reaction time and accuracy were differentially affected by explicit knowledge. These findings indicate that implicit sequence learning occurs independently of explicit knowledge, and help to explain previous discrepant findings.     

初中男生个体攻击性与群体攻击性的差异

运用实验法和问卷法对118名初中男学生进行攻击性的研究.比较了四种不同类型的攻击行为.包括群体之间、个体之间、群体与个体之间、个体与群体之间.结果显示:群体无论是作为攻击来源还是攻击目标都能起到增加攻击行为的情境作用;个体之间与群体之间在攻击性方面有显著差异;群体之间相互作用时表现出的攻击性远高于个体之间相互作用时表现出的攻击性:个体与群体相互作用时比个体之间相互作用时表现出更高的攻击性.     

4～5岁儿童一一对应任务中的比例效应

一一对应和数量比较是幼儿数概念发展的两个重要方面。在本研究中．40名4岁和39名5岁的儿童分别完成了不同比例数量的一一对应任务和数量比较任务。结果表明：（1）两种实验任务下均出现比例效应．说明儿童在解决一一对应问题时,仍然用数量比较的方法来进行判断;（2）任务类型的主效应显著,一一对应任务下的正确率要显著低于数量比较任务下的正确率;（3）知觉线索更多地影响数量比较任务。     

大学生A型行为类型及其学业情绪特点

用A型行为类型量表和大学生一般学业情绪问卷对218名大学生进行了调查。结果发现：被调查大学生中A型行为者（A和A^-）约占25％。大学生的学业情绪以正性情绪为主,A型行为者的比例和学业情绪的得分在性别、年级、专业变量上无显著差异。不同行为类型者学业情绪的特点：B型者（B或B^-）的羞愧、气愤、厌烦、焦虑、自豪、希望、愉快情绪均明显低于A型者（A或A^-）;B型者（B或B^-）的羞愧、气愤情绪明显低于极端中间型者;TH得分高者负性情绪多而不能放松;CH得分高的学生既有羞愧和气愤,又有自豪和希望。     

On ethical order

The existent ethical relationships are the result of the historical amalgamation of objective and subjective conditions. Ethical relationships are essential relationships in the real and rational order, which are maintained by a system of regulations on morals, laws and customs, and infused with a spirit of subjectivity. Rationality and legitimacy are the primary concerns of those relationships. A distinction between morals and ethos needs to be made when studying ethical order. Sound ethical order lies in effective regulation of morals and effective control of law. In the process of social reform, ethical order promotes social development through the dialectical movement of freedom and necessity. A harmonious society is a society which is based on legitimate and just ethical order. Translated by Cui Hui from Lunlixue yanjiu 伦理学研究 (Studies in Ethics), 2007, (5): 1–8     

If It's Difficult to Pronounce, It Must Be Risky

ABSTRACT— Low processing fluency fosters the impression that a stimulus is unfamiliar, which in turn results in perceptions of higher risk, independent of whether the risk is desirable or undesirable. In Studies 1 and 2, ostensible food additives were rated as more harmful when their names were difficult to pronounce than when their names were easy to pronounce; mediation analyses indicated that this effect was mediated by the perceived novelty of the substance. In Study 3, amusement-park rides were rated as more likely to make one sick (an undesirable risk) and also as more exciting and adventurous (a desirable risk) when their names were difficult to pronounce than when their names were easy to pronounce.

Sensation seeking and danger invulnerability: Paths to college student risk-taking

This study examines the roles of sensation seeking and invulnerability as predictors of health compromising behaviors in a multiethnic sample of 1690 emerging adult college students (mean age = 19.8, range 18–25 years) from nine US colleges and universities. Participants completed the Arnett Sensation Seeking Inventory and the Adolescent Invulnerability Scale; and reported how often they had participated in a set of health compromising risk behaviors (i.e., substance use, impaired driving, and sexual behaviors) in the 30 days prior to assessment. Sensation seeking and danger invulnerability scores were moderately correlated (r = .30). Findings from a series of multivariate Poisson regression analyses suggest that when considered simultaneously as predictors, sensation seeking appears to be a general risk factor associated with engagement in a variety of risk behaviors, whereas danger invulnerability is primarily a factor in those risk behaviors that are less common among peers (e.g., hard drug use, casual sex, and driving while intoxicated).     

康德、黑尔与普遍主义

康德和黑尔都是伦理学的杰出代表人物,尽管一个是规范伦理学家,一个是元伦理学家,但是双方都把目光聚集在道德的形式主义研究上,并且着力于普遍主义的落脚点.两者在理论上存在诸多不同,却依然可以发现两者在理论上的先行后继的关系.
